Woy Woy Landfill Gas Abatement Facility

Woy Woy Landfill Gas Abatement Facility is an electricity generation from landfill gas project located at the Woy Woy Waste Management Facility on the Central Coast of New South Wales, approximately 80km north of Sydney and just south of Gosford. It was registered in August 2013 and operates within the designated boundaries of the municipal landfill site.

Electricity generation from landfill gas projects involve installing and operating a gas collection system to capture methane-rich biogas generated by the decomposition of both legacy and non-legacy organic waste. As a standard methodology requirement, this captured methane, a highly potent greenhouse gas, is sent to a combustion device where it is destroyed and converted into renewable electricity, rather than being allowed to vent into the atmosphere.

The Woy Woy area is part of the coastal Central Coast region, where the primary land use revolves around residential settlements, municipal waste management, and large tracts of native vegetation and national parks. The region is classified as having a humid subtropical climate with moderate to high coastal rainfall. The typical soil profile of this coastal area consists of Hawkesbury sandstone-derived soils, coastal sands, and underlying clay layers.

The project has a rich administrative history, having transitioned through three different methodology variations (2012, 2015, and the most recent 2021 electricity generation compilation) to remain compliant with evolving carbon accounting standards. It successfully completed a major Fixed Delivery carbon abatement contract (CAC210760) with the Commonwealth in June 2022, fulfilling a massive commitment of 130,000 Australian Carbon Credit Units (ACCUs). Furthermore, in November 2023, the project changed hands when the proponent role was transferred from AGL Energy Services Pty Ltd to LMS Energy Pty Ltd, one of Australia’s leading landfill bioenergy operators.
